Do any of you guys happen to know of a really good Voice modulator I could download on the Play Store that changes your voice in all ways? I've been hoping to play with one so I can sound like my favored Playable Disney Infinity characters or other fictional characters.

The only good voice changer I've ever used was DSi Sound (I think it was called) for the DSi. I'm pretty sure there's a similar app on the 3DS, too. It's completely free, as long as you have a DSi or 3DS. You can change slowness/quickness and pitch in so many different ways, and you can add effects like robot, tunnel, and walkie-talkie.
